This same book talks of "constrictor knots", used to repair such things
as split tillers. Hmm. This could work.

So, I replaced the metal ferrule with a double constrictor knot made of
nylon cord, all well daubed with Pliobond rubber cement. We'll see how
well this works, but it ought to be permanent.

Followup: It failed already - the constrictor knot just slid off the cable.
Probably due to the heat of the lamp softening things. I’ll probably make
some kind of tight-fitting swage collar of metal.

Have you considered NOT hanging the lamp by the cord? It has always
seemed to be a short waiting to happen, as the knots slip out,
knocking off the poorly applied wire nuts...

Well ... there is the "Underwriter's Knot", which used to be
used to keep wires from pulling out of fixtures -- back before things
like the Heyco strain relief nuts replaced grommets. (And the knot did
not even require a special tool, unlike the Heyco strain relief nuts.

O.K. This site gives a video:
